my Letters Patent No. 1,O69,99 4 patentcd Augu t 12, 1913, and I?o.l,0"('l,5 l2 patented in 26, 1913; andthe object of the present improvement is to "further simplify and strengthen iny joint-fastening so that while it s self-locking, it provides as it were a danible truss construction in its wedging arrangement while occupying an exceedingly small amount of space, therebyaccoim plishing the greatly desirable qualities in a 'i'rzstening oil this type, that is, a joint fastening of great strength which occup es small space and particularly as to the depth or thickness of the fastening so that when placed on the rear side of a dresser or other article oi furniture, it does not project and mar the we or other surfaces against which the articl e of furniture may be placed; and the invention consists in the novel features d combinations hereinafter set forth and laimed.

the drawings, Fi 'ure 1 shows an elevaoi the furniture fastening attached to 1 different parts of a piece of furniture to :ch one part to the other. Fig. 2 is a an View of the two inter-engaging parts of the fastening with their spaced return bend inturned flanged edges. Figs. 3 and 4 show a plan View, and edgewise and end elevations of the new form of wedge with its le -thwise tapered spaced outturned flanged (a s. l 5 is an end elevation of the complete joint-fastening with the wedge 1n posit" m in the inter-engaging portions of said fastening; and Fig. 6 is a lengthwise sectional view of the same at line 6-6 in Fig. 1 showing the fastening attached to two portions or a piece of furniture and showing the central interlocking ends of the engaging parts and the wedge extendlng down over and locking the same in the engaged position; and Fig. 7 is a lengthwise secrustic aarrnsrown, nnw roan.

View atlinefP-T l Showing The joint-fastening consist-s oi the upper I outwardly flanged attaching plate 10 with the spaced interned return bend edges 11 with the bottom end flange 12 in the crosswise spaced position cent-ral therebetween; and the lower outwardly flanged attaching plate 13 with the len thwise spaced inturned returirbendedges 14 similar to plate 10 and .in alinernent with the spaced return-bend edges oi'said plate 1 0,and a spacedreturn bend hooked flange 15 intermediate between the flanges lccrosswise on the end adjacent the flange 12 to hook over the same in bolding engagement.

The interengaging attaching plates 10 and 13 are provided with attaching screw holes 16 for attachment to parts '22 and 23 each side oi the furniture joint in interhooking relation as shown in Figs. 1 and 6. This brings the spaced return bend flanged lengthwiseedges 11 and 14: into alinement so as to provide a continuous lengthwise flange on each edge which turns outwardly from the. surfaces of the "furniture parts and then inwardly in spaced return bend aline-' ment to a spaced distance from the surfaces of" the plates 10 and 13 as shown at 1 8.

The wedge 19 comprises the channelshaped central portion 20 and the spaced out-turned tapered flanged edges 21 and 22 which engage beneath. the spaced return bendfianged edges 11 and 14 at each side so that when driven to place, each of said return bend edges forms as it were a tubular holding portion substantially vas strong as in my former furniture fastenings, in addition to the central bridging channel-shaped portion 20 which extends down over the interhoolring portions 12 and 15, looking them firmly in the interengaging position, as shown in my application for LettersPatent, Ser. No. 536,792, filed February 15, 1922.

It is apparent that the construction permits the flattening of all the parts so that the complete three-part furniture fastening when assembled in holding position takes a minimum amount of space with greatly increased holding strength and consequent rigidity in the holding ofthe parts 22 and each side of the joint 17.

lit is apparent that each of the threeparts 10, 13 and 19 can bequieklyuand economically struck up from the sheet metal by means of suitable dies, .thereby"providing an exceedingly strong and convenient furnitnre fastening at low cost.

lVhat is claimed as new is:

1. In a furniture joint fastening, a-pair 0t members arranged in end to end relation and eaeh having .a body and side flanges which latter extend outwardly and then inwardly over the bodies and have their free edges extended inwardly towardand spaced from the bodies interengaging means between the adjacent ends of the members, and a wedge composed of a. metal plate having its sides turned outwardly at approxirnately ri t angles and then turned to lie I A l/1.996

wardly turned parts of the plate being longitudinally inclined to wedge against the inwardly extending parts of the side flanges 4 of the bodies.

2. Inia furnitnrejioint fastening, a pair of members arrangedin end to end'rela- "tion' and-'eaeh-rha ving side flanges which extend outwardly and inwardly and finally towards the be'dies ofsthe members in spaced relation to the bodies, to form side flanges of approximate ll-shape in eross-seeti-omdn on the bodies of-the m6-1"flb6'!'S -whiehei'igage between the --ontwardly and-inwardly extending parts 0t thejtl shaped side flanges ofthe inenibers; the iree edges of the J- shaped sides of the wedge being longitudinally inclined 'to "wedge against the inparts of the side flanges war'dly extending
